Because God is so concerned for the holiness of His people, they should be equally concerned. The church cannot preach and teach a message it does not live and have any integrity before God, or even before the world. Yet in many churches where there is no tolerance for sin in principle there is much tolerance for it in practice. And when preaching becomes separated from living, it becomes separated both from integrity and from spiritual and moral effectiveness. It promotes hypocrisy instead of holiness. Divorcing biblical teaching from daily living is compromise of the worst sort. It corrupts the church, grieves the Lord, and dishonors His Word and His name.
